Thousands of legitimate files are being blocked and removed from users' Mega accounts, even when the file is legal for sharing, according to a report.

TorrentFreak tested the situation, uploading a number of files free for sharing, including, amusingly, a video explaining fair use and a copy of Mega founder Kim DotCom's own music single. All were removed within minutes, with TorrentFreak receiving e-mails from Mega explaining that a take-down notice had been issued on the files.

The problem is that Kim DotCom recently took to Twitter to claim that Mega was receiving only 50 copyright take-down notices a day, which doesn't explain the number of files being removed.
